Game of Isomers: Bifurcation in the Catalytic Formation of Bis[1]benzothieno[1,4]thiazines with Conformation-Dependent Electronic Properties

Two regioisomers of bis[1]benzothieno[1,4]thiazine are unexpectedly obtained by tuning the catalytic conditions of the intermolecular-intramolecular Buchwald-Hartwig amination. Mechanistic insights and evidence of intermediates support a conclusive mechanistic rationale. Furthermore, a computationally based study on the influence of conformational aspects on the HOMO energy level of anellated 1,4-thiazine paves the way to enhance the electronic properties, thus successfully achieving higher luminescent and easier oxidizable syn-syn bis[1]benzothieno[1,4]thiazines.

Syntheses, characterization, redox properties, and mixed-valence chemistry of tetra- and hexanuclear diyndiyl complexes

A series of Ru2IIFe2II heterotetranuclear sigma-acetylide complexes [{Cp(dppf)Ru} 2(C?C-R-C?C)] (dppf = 1,1′-bis(diphenylphosphino) ferrocene, R = 0, 1; 1,4-benzenediyl, 2; 1,4-naphthalenediyl, 3; 9,10-anthracenediyl, 4) were prepared and characterized by elemental analyses, ES-MS spectrometry, IR, 1H and 31P NMR, and UV-vis-NIR spectroscopy, and cyclic and differential pulse voltammetry. Reaction of 1 with [Cu(MeCN)4](ClO4) gave Ru2II-Fe 2IICu2I heterohexanuclear compound [{Cp(dppf)Ru}2{Cu(MeCN)}2(C?C-C?C)](ClO 4)2 [5(ClO4)2] through pi-bonding of the acetylides to CuI centers. The structures of 1 and 5(ClO 4)-(SbF6) were determined by X-ray crystallography. Chemical oxidation of 1, 3, and 4 with an equivalent of ferrocenium hexafluorophosphate gave one-electron-oxidized species [{Cp(dppf)Ru} 2(C?C-R-C?C)](PF6) [R = 0, 1a(PF6); 1,4-naphthalenediyl, 3a(PF6); 9,10-anthracenediyl, 4a(PF 6)] with Ru2II,III mixed valence. Electrochemical and visible-infrared spectral studies revealed that the electronic delocalization depends on the R substituent in the bridging ligand C?C-R-C?C. While the mixed-valence compound 1a(PF6) (R = 0) displays an electronically delocalized behavior (class III mixed-valence system), 3a(PF6) (R = 1,4-naphthalenediyl) and 4a(PF6) (R = 9,10-anthracenediyl) may belong to borderline compounds between electronic localization and delocalization.

Reactions of [RhRu3H(eta5-C5Me5)(CO) 9BH2] with didentate phosphines and the synthesis and crystal structure of [RhRu3H2(eta5-C5Me 5)(CO)8(mu-dppf-P,P?)AuB] [dppf = 1,1?-bis(diphenylphosphino)ferrocene]

Ligand-substitution reactions of [RhRu3H(eta5-C5Me5)(CO) 9BH2] with the didentate phosphines dppf and dppa yielded compounds of the type [RhRu3H2(eta5-C5Me 5)(CO)8(L-P)BH] [L = 1,1?-bis(diphenylphosphino)-ferrocene (dppf) or bis(diphenylphosphino)acetylene (dppa)] with the P-donor ligand replacing one CO ligand in a butterfly wingtip site. Spectroscopic data indicate that a redistribution of cluster hydrogen atoms occurs during CO ligand substitution. Subsequent reaction of [RhRu3H2(eta5-C5Me 5)(CO)8(dppf-P)BH] with [N(PPh3)2]Cl and [Au2Cl2(dppf)] yielded [RhRu3H2(eta5-C5Me 5)(CO)8(mu-dppf-P,P?)AuB], but there was a competitive intramolecular substitution reaction to give [RhRu3H3(eta5-C5Me 5)(CO)7(mu-dppf-P,P?)B]. The gold cluster has been characterised by single-crystal X-ray crystallography. The RhRu3B core is straddled by a {Au(dppf)} unit which co-ordinates to a wingtip ruthenium atom through a phosphorus atom whilst the gold centre bridges the ruthenium-boron edge. Possible routes to the formation of [RhRu3H2(eta5-C5Me 5)(CO)8-(mu-dppf-P,P?)AuB] have been investigated.

Iridium and platinum complexes of Li+@C60

Iridium and platinum complexes of the lithium cation encapsulated fullerene Li+@C60 were synthesized and structurally determined. The encapsulated Li+ strengthens the pi back-bonding from the transition-metal center to the fullerene cage and is attracted toward the two negatively charged carbon atoms bound to the transition metal in the solid state.

Assembly of cyclopalladated units: Synthesis, characterisation, X-ray crystal structure and study of the reactivity of the tetrametallic cyclopalladated complex [Pd{C6H4-CH=N- (C6H4-2-O)}]4·2CHCl3

The reaction of the equimolar amounts of the Schiff base C6 H4-CH=N-(C6H4-2-OH) (1) and palladium (II) acetate in refluxing methanol for 2 h produces [Pd{C6 H4-CH=N-(C6H4-2-O)}]4 (2)·2CHCl3. The X-ray crystal structure of 2·2CHCl3 reveals that it contains a central non-planar eight-membered ring “Pd4O4” formed by the self-assembly of four cyclopalladated fragments in which the ligand behaves as a [C, N, O]2- terdentate ligand and the oxygen atoms act as bridges between the monomeric units. The reaction of 2 with triphenylphosphine or 1,1?-bis(diphenylphosphino) ferrocene (dppf) produces the opening of the central “Pd4 O4” core and the formation of the monomeric derivative [Pd{C6H4-CH=N-(C6H4-2-O)} (PPh3)] (3)·CH2Cl2 and the trimetallic complex [{Pd[C6H4-CH=N-(C6 H4-2-O)]}2(mu-dppf)] (4), respectively. In 3 and 4, the ligand also behaves as a dianionic and terdentate [C, N, O] 2- group, thus indicating that the Pd-O bond exhibits remarkable stability. The X-ray crystal structure of 3· CH2Cl2 confirmed the mode of binding of the Schiff base and a trans arrangement between the imine nitrogen and the PPh3 ligand. A comparative study of the spectrochemical properties of compounds 2-4 is also reported.

Aryl-CF3 Coupling from Phosphinoferrocene-Ligated Palladium(II) Complexes

This article describes a detailed investigation of ligand effects on Ph-CF3 coupling from phosphinoferrocene-ligated PdII(Ph)(CF3) complexes. This study reveals that increasing the size of the phosphine substituents results in an enhanced rate of Ph-CF3 coupling, with (DtBPF)Pd(Ph)(CF3) (DtBPF = 1,1?-bis(di-tert-butylphosphino)ferrocene) being the most reactive complex. The mechanism of Ph-CF3 bond formation from both (DtBPF)Pd(Ph)(CF3) and (DiPrPF)Pd(Ph)(CF3) (DiPrPF = 1,1?-bis(diisopropylphosphino)ferrocene) was interrogated experimentally and computationally. These studies implicate a pathway involving concerted Ph-CF3 bond-forming reductive elimination from the four-coordinate PdII centers. An alternative pathway involving alpha-fluoride elimination and subsequent PhF2C-F coupling from PdII(CF2Ph)(F) intermediates was also evaluated but was ruled out based on DFT as well as the independent synthesis and reactivity studies of (DiPrPF)Pd(CF2Ph)(F).

Novel types of tetra-, hexa-. octa-. and dodecanuclear silver clusters containing (2,7-Di-tert-butylfluoren-9-ylidene) methanedithiolate

The reaction of AgCIO4 with piperidinium 2,7-di-tert-butyl-9H- fluorene-9-carbodithioate (pipH)[S2C(t-Bu-Hfy)] (1) (t-Bu-Hfy = 2,7-di-tert-butylfluoren-9-yl) afforded [Agn{S2C(t-Bu-Hfy) }n] (2), which reacted with phosphines to give [Ag{S 2C(t-Bu-Hfy)}L2] [L = PPh3 (3a); L2 = bis(diphenylphosphino)ethane (dppe, 3b), 1,1?-bis(diphenylphosphino)- ferrocene (dppf, 3c). By reacting complex 2 with AgCIO4 and piperidine in a 1:1:1 molar ratio, the dodecanuclear cluster [Ag 12{S2C=(t-Bu-fy)}6] (4) (t-Bu-fy = 2,7-di-tert-butylfluoren-9-ylidene) was obtained. Compound 4 can also be directly prepared from the reaction of 1 with AgCIO4 and piperidine in a 1:2:1 molar ratio. The reactions of 1 with AgCIO4, phosphines, and piperidine afforded the compounds [Ag6{S2C=(t-Bu-fy)} 3L5] [1:2:2:1 molar ratio; L = PPh3 (5a), P(p-To)3 (5b)], [Ag4{S2C=(t-Bu-fy)} 2(dppf)2] (6) (1:2:1:1 molar ratio), [Ag n{S2C=(t-Bu-fy)}n/2{P(i-Pr)3} n] (7) (1:2:2:1 molar ratio), or [Ag8{S 2C=(t-Bu-fy)}4{P(i-Pr)3}4] (8) (1:2:1:1 molar ratio). Complexes 5a, b, 6, 7, and 8 can be also obtained by reacting 4 with the corresponding phosphine in the appropriate molar ratio. The crystal structures of 4, 5b, and 8 have been determined by X-ray diffraction studies. The nuclearity of complex 6 was established from its 31P{1H} NMR data, which reveal a very fast dynamic process leading to an average coupling of each of the P atoms of the dppf ligands with four Ag atoms.
